IMPROVEMENT IN SAW-HANDLES.

Speeification forming part of Letters Patent N0. 175,268, dated March28, 1876; application filed February 12, 1876.

T0 all whom lt mag concern Be it known that I, EBEN MOODY BOYN- TON,ofWest; N ewbury, in the county of Essex and State of Massaehusetts,have invented Eig. 3, a seetion on the line w x of Fig. l, and

Fig. 4 a seetional view of my improved handle.

The object of this invention is 130 produce, first, a lightcrosseut-sawfor cutting ofi pieces of heavy tin1be1, logs, &e. whieh may becouvenieutly handled by one person; second, a ready, eheap, and simplemeans of attaehing the handles to the blades; am], third, a means bywhieh files 01 other small tools, whieh are neeessary or desirable tocarry with the saw, may be conveniently earried.

ln o rder to afl'ordmeans for producing the necessary downward pressureupon the saw I first provide a handle, B, of the same f0rn1 as that ofan ordinary hand-saw, and then seeurethereto an upri ght handle, (J, asshown in Figs. land 2. lt will be seen that by this arrangementthehandleB serves for drawing the saw back and forth, while, by pressingforward upon the handle O, (it being above -the blade 0t' the saw,) theteeth will be foreed down into the wood, it only being necessary t0 itssuceesst'ul operation that the blade shall be Sllfficiently stiff tosustain itselfand prevent buckling.

The next feature 0f nny invention is the manner 0f actaching the handlesabove mentioned to the blade. ln order t0 accomplish this result Iprovide a handle, B, Whieh, as before stated, is of the form commonlyused onhandsaws, and leere throngh the san1e, from top t0 bottom, ahole, e, as shown in Figs. 2 and 3,

- and cnt from said hole to the forward end 0f the handle a slit; ofsufficient width t0 reeeive the blade A, as shown in Fig. 3. The blade Ais provided ab its back end, at the top, with an ear, c, and at thebottom wil;h a corresponding ear,d, the object ofwhieh willbeexplainedhereaf'tm. 1 next provide a handle, G, having a metal rod 01 holt, n,passing through it from end t0 end, and extending some distance belowthe lower end of said handle, where it: terminates in a serew-thread, asshown in Fig. 2. The handle C rests :xt its lower end upon a 001- lar,b, which is seated upon the handle B, said collar having 0n its underside a reeess t0 receive the ear cofthe blade A, as shown in Fi g. 2.'lhe 1'0d 01' holt n 0f the handle O. asses through the eollar b, anddown into the hole e, als the lower end of whieh it entern a hole in theupper end of the hook o. The hook 0 engages over the ear d of the blade,as shown in Fig. 2; and it: will therefore be seenthat when the handle Cis tnrned the serew cifithe rod n will draw the hook 0 toward the collarb, thereby firmly seeuring the handles to the blade, and to each ther.The collar bis seated upon the handle B in such manner as to be madestationary, and is provided 0n its npper faee with an upright flange, f,whieh projeets into the open end 0f the ferrule a 011 the handle C,thereby keeping the parlzs in position, and at the sa1ne timepermitt-ing the handle0 to tnrn readil v 0n the collar b. I also providea couvenient reoeptacle for files and other small tools, which it isvery desirable t0 earry with the saw. T0 do this I 1nake the uprighbhandle O hollow, as shown in Fig. 4, and furnish it with a screw-cap, D.When the hollow handle D is used it is, of eourse, necessary that therod n should not extend throngh the entire handle, bat with a head 01enlargernent, z, as shown in Fig. 4, formed upon it it is forced intothe handle 0 from its open end until it becomes seated in the lower end0f the same, when it: is secured. in plaee by a pin, k, the 1'0d nprojecting from the handle G, as in the solid handle.

If desired, one er more rivets, g, may be passed through the handle B,130 prevent its splitting, a noteh, h, being 01113 in the rear end ofthe saw for eaeh rivet, they serving the further purpose 0f preventingthe handle B from dropping down, away from the handle O, laut this isnot eonsidered neeessary, as the hook 0 may be made 130 aecomplish thesame pnrpose.

dles B and G, construcbed and arranged to operate substantially as shownand described.

2. In combination with the sa.w A, provided with the ears c and d, thehandle B, provided with the hole e, and the handle O, provided with thecollar b and :claluping-hook o, all constructed to operate substantiallyes descrihed.

3. 'lhe tubular handle O, provided with a screw-cap, D, a.nd the holt nand hook o, the whole constructed .toopexrateas :and for the purpose setforth.
